1-16 Byron Court

Block of sixteen flats built between 1954 and 1956 by Eric Lyons for Bargood Estates Ltd (subsequently Span Developments Ltd), with Geoffrey Paulson Townsend as developer, G Scoble as project architect, and Wates Ltd as builder.

The development comprises two main elements. The lower block uses crosswall construction with brick partitions, while the higher block features brick end walls and partitions with concrete and tile hanging, and Eternit block. Both have flat felted roofs and brick stacks.

The principal three-storey block forms an H-plan with twelve flats arranged around a centre entrance and stairwell. The entrance front is dominated by four fully glazed tiers of windows in metal panes, with the open entrance positioned to the right side. The ground floor entrance is masked by a covered timber walkway bearing the block's name. Flanking the glazed entrance are concrete lattice panels ventilating the drying rooms. The rear centre facade presents a tripartite composition of concrete lattice ventilation panels incorporating a projecting dustbin store.

The flank walls display continuous horizontal glazing in timber frames, divided by tile hanging. The windows throughout are also timber-framed. The four bay side walls accommodate principal rooms, marked on the first and second floors by groups of three windows with two deeper units featuring window boxes, divided at sill level, and one of the pair with a top-opening casement. The ground floor alternates between three windows per bay—one fully glazed with French windows, the others resembling those above with a sill rail. Tile hanging separates each storey. The brick end walls have one square window towards the centre on each floor.

The staircase hall serving flats 5-16 contains an impressive open well concrete staircase with terrazzo stairs and landing, steel balustrades, and timber panels to the first flight and landings. The flats originally had timber floors.

The two-storey wing contains five bays divided by exposed ends of crosswall, with both facades featuring full-width windows of three square panes per bay, some with top-opening casements. Storeys are divided by tile hanging. The central entrance has large plate glass windows divided at sill level to the front and an entrance-way to the ground floor at the rear, with a vertical staircase window of two panes to the first floor and louvres to both storeys. Other bays are mirrored in composition around the centre. The front elevation has two deeper windows in corner bays, divided at sill level with window boxes and one outermost blind window; the rear has an innermost blind window, then a tripartite composition with central top-opening casement and blind windows in the centre of end bays. The staircase hall to flats 1-4 has paved floors, terrazzo stairs, and steel balustrades with timber panels to the first flight and landing. Timber doors with green glazing serve store rooms.

Byron Court is one of the most complex groups within the Parkleys development, the first and largest of Span's influential private schemes. Eric Lyons and Geoffrey Townsend had met in the late 1930s and renewed their partnership after wartime service, developing small private schemes in south-west London and north Surrey until 1954, when Townsend established himself as a developer. This was their first mature work as Span Developments Ltd.

The development occupies the site of a former nursery. The blocks were carefully laid out to preserve existing trees, and the nursery stock and its gardener were taken over as part of the development. The scheme is arranged as a series of cul-de-sacs, with the taller blocks functioning as distinctive focal points within the lower development's grid. The combination of two- and three-storey blocks is distinctive to Parkleys, as is the use of brick and tile hanging, a material combination subsequently repeated in Span works, particularly at Blackheath. The concrete panels in the taller block represent Lyons's most distinctive design in the contemporary idiom. The lower block's mixture of traditional materials used in a modern manner created a particularly humane environment that was widely admired.

Lyons's terraces present a modern vernacular response to the Georgian tradition of central London, set within lush suburban landscaping at relatively high densities of approximately 80 persons per acre, which frequently brought Span into dispute with planning authorities. Parkleys was developed for first-time buyers and marked one of Span's early promotions of the endowment mortgage. It was also the first example of Span's residents' management company system, which has maintained many of their developments in exceptional condition. Each leaseholder contributes to funding paid maintenance staff and serves as a member of the management company running the estate.
